[0029] Example 1: In some embodiments, please refer to the accompanying drawings of the specification. Figure 1-Figure 3 , a raw material conveying device for powder coating production, comprising a supporting truncated table 1, a material blocking assembly 2 and a material transfer barrel 3;

[0030] A feeding pipe 11 for cooperating with a conveying pipe to convey the powder into the transfer bucket 3 is fixedly installed on the upper side of the support circular platform 1.

The pressure-equalizing component is installed on the support circular platform 1, and the dust-proof component is connected to the pressure-equalizing component.

[0031] The lower side of the support truncated platform 1 is provided with a dustproof mounting assembly 13 that can be mounted on a material transfer barrel 3 of different opening sizes; the lower side of the support truncated platform 1 is provided with a material blocking assembly 2;

[0032] The material blocking assembly 2 is installed on the lower side of the supporting truncated table 1 , and the material blocking assembly 2 is used to control the opening and closing of the feed pipe 11 .

[0033] In this embodiment, when the raw material conveying device for powder coating production is working normally, the dust-proof mounting assembly 13 at the bottom of the supporting table 1 covers the opening of the material transfer barrel 3, thereby preventing the powder from flying out when the powder coating is transferred to the material transfer barrel 3; the setting of the dust-proof mounting assembly 13 enables the device to adapt to material transfer barrels 3 of various sizes; when in use, the outlet of the conveying pipe, such as the pneumatic conveying pipe, is connected to the feeding pipe 11, and then the conveying pipe conveys the powder coating to the material transfer barrel 3 through the feeding pipe 11; in this process, the air pressure in the material transfer barrel 3 is kept balanced by the dust-proof pressure equalizing assembly 12, so that the gas can be discharged smoothly through the dust-proof pressure equalizing assembly 12, and at the same time, the dust-proof pressure equalizing assembly 12 is used to discharge the gas. Component 12 blocks the powder coating from splashing out, thereby preventing the powder coating from flying to the outside during the transportation process; after the transfer barrel 3 is full of powder coating, the blocking component 2 is operated to block the bottom of the feed pipe 11 and the dust-proof pressure equalizing component 12, thereby preventing the powder coating in the feed pipe 11 and the dust-proof pressure equalizing component 12 from falling and flying to the outside when the support table 1 is moved up and away from the transfer barrel 3; then the transfer barrel 3 filled with powder coating is removed, and the empty transfer barrel 3 is moved to the lower side of the dust-proof mounting component 13, and the transfer barrel 3 is fastened by the dust-proof mounting component 13, and the blocking component 2 is reset, thereby realizing continuous transportation of powder coating to different transfer barrels 3 and preventing powder from flying to the outside.

[0034] Embodiment 2: In some embodiments, as Figure 1-Figure 5 As shown, as a preferred embodiment of the present invention, the dustproof mounting assembly 13 includes a plurality of annular plugs 131, and the plurality of annular plugs 131 are arranged on the bottom surface of the supporting table 1. The plurality of annular plugs 131 are concentrically arranged and have different radii; an annular slot 132 is formed between adjacent annular plugs 131 to be clamped with the opening edge of the material transfer barrel 3.

[0035] The pressure equalizing assembly includes an air outlet cylinder 124 , which is disposed on the upper side of the supporting truncated platform 1 . An air outlet 125 in the air outlet cylinder 124 is provided in the air outlet cylinder 124 and is funnel-shaped and passes through the supporting truncated platform 1 from top to bottom.

[0036] The dustproof assembly includes a dustproof cloth 121 and a locking frame 122. The dustproof cloth 121 covers the top of the air outlet 124.

[0037] The bottom of the feed pipe 11 is lower than the bottom of the annular insert 131 ; the bottom of the gas outlet 125 is higher than the bottom of the annular insert 131 .

[0038] The feed pipe 11 and the dust-proof pressure equalizing assembly 12 are both located inside the annular insert 131 .

[0039] The material blocking assembly 2 includes a turntable 21 and a rotating assembly. The middle part of the turntable 21 is rotatably installed on the bottom of the supporting table 1. A first circular hole 22 is opened on the turntable 21 to align with the feed pipe 11. A second circular hole 23 is opened on the turntable 21 to align with the air outlet 125. The rotating assembly is fixedly connected to the turntable 21 and is used to drive the turntable 21 to rotate.

[0040] The rotating assembly includes a vertical cylinder 24 and a dial plate 25. The lower end of the vertical cylinder 24 is fixedly connected to the edge of the turntable 21, and the upper end of the vertical cylinder 24 is fixedly connected to the inner end of the dial plate 25.

Then, after the air flow is discharged upward through the air outlet 125, the powder coating in the air flow is blocked by the dustproof cloth 121 at the upper end of the air outlet cylinder 124; thereby ensuring the balance of air pressure while preventing powder from flying to the outside;

[0042] After the transfer barrel 3 is fully loaded, the dial plate 25 is rotated, and the dial plate 25 drives the vertical cylinder 24 and the turntable 21 to rotate, so that the first circular hole 22 is no longer aligned with the feed pipe 11, and the second circular hole 23 is no longer aligned with the air outlet 125, so that the bottom of the feed pipe 11 and the air outlet 125 are blocked by the turntable 21, preventing the powder in the feed pipe 11 and the air outlet 125 from falling when the transfer barrel 3 is replaced.

[0043] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
